Impatiens plant named ‘Silte Redsar’

ABSTRACT

A new  Impatiens  plant particularly distinguished by double, rose-shaped, red and white flowers, semi-compact, upright, outwardly spreading and mounded plant habit, free flowering, good basal branching, and moderately vigorous growth habit, is described.

Genus and species: Impatiens walleriana.

Variety denomination: ‘Silte Redsar’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Impatiens, botanically known as Impatiens walleriana, and hereinafter referred to by the cultivar name ‘Silte Redsar’. The new cultivar originated from a hybridization made in June 2004 in Andijk, The Netherlands. The female parent was the proprietary red star-flowered Impatiens plant ‘ID04-377-1’ (unpatented), while the male parent was the proprietary red star-flowered Impatiens plant ‘ID03-1913’ (unpatented). The seeds produced by the hybridization were sown in September 2004. A single plant selection was chosen for further evaluation and for asexual propagation in December 2004.

The new cultivar was created in 2004 and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands and Gilroy, Calif. over a two-year period. The plant has also been trialed at Gilroy, Calif., Andijk, The Netherlands and Hillscheid, Germany. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for the European Union on Dec. 14, 2006.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Andijk, The Netherlands.

-   -   1. Double, rose-shaped, red and white flowers;     -   2. Semi-compact, upright, outwardly spreading and mounded plant         habit; and     -   3. Free flowering, good basal branching and moderately vigorous         growth habit.

DESCRIPTION OF PHOTOGRAPHS

This new Impatiens plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a whole plant about 10 to 12 weeks old, grown in a greenhouse in Hillscheid, Germany during the spring. The photographs were taken in May 2006.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Silte Redsar’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. in a trail setting. The plant history was taken on 26-week old plants grown in 6-inch containers in a greenhouse during the fall and winter seasons. The plants had one plant growth regulator treatment and one terminal pinch after cuttings were transplanted. Color readings were taken under natural light in the greenhouse in January. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001). Texture description data was viewed with a dissecting microscope.
